Abstract (en)
This invention relates to a shifting device for a synchromesh-type transmission. The subject to be solved by the present invention is to detect an accurate change of the input rotation at each area of the shifting operation, and to set the applying load to the shifting fork based on the change of input rotation. The shifting device for synchromesh-type transmission of the first invention is comprised of a detecting means for detecting a rotation change rate of an input shaft, a judging means for judging a balk point based on the rotation change rate of the input shaft detected by said detecting means, and a transmission controlling mechanism including a driving means electric-controlled for driving a shift actuator to shift the shift fork, the driving means controlling a drive current to the shift actuator when the balk point is detected bythe judging means. <IMAGE>
